And it seems one of the ways Goldie Hawn stays so youthful is by keeping in shape.

The actress opted to use her high fitness levels for a good cause on Sunday when she took part in a charity bike ride to raise awareness for cancer.

Goldie cycled 30 miles as part of a challenge to raise funds for the University of Miami Sylvester Comprehensive Cancer Center.

She kept the rays out of her face with a pair of sunglasses and ensured she stayed safe by sporting a helmet during the ride.

The star is in sunny Miami after she was spotted jetting out of LAX airport in Los Angeles on Thursday.

It seems she has taken the trip solo as she has not been spotted with her long-term partner Kurt Russell.

Goldie already had two children, Oliver and film star Kate, from her marriage to Bill Hudson when she got together with Kurt, who she recently discussed in an interview with Radio 4's Desert Island Discs.

Although they have never married, the couple – who have a 26-year-old son, Wyatt, together – are still going strong and the Private Benjamin star says it’s down to the fact they both work hard at their relationship.

She said: 'We’ve been together for 29 years now and I think if two people want to make it work, you make it work but if one doesn’t, then you’re sunk.

'I don’t know if it’s been hard work, but that’s all I wanted out of life – a good relationship, a healthy family of mind and body and I feel very honoured that this happened. But you do have to put your time in.'
